Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 and 2 are views showing an example of a cigarette inserted into an aerosol-generating device.
Referring to fig. 1 and 2, the aerosol-generating device 10 includes a battery 120, a control portion 110, a heater 130, and a vaporizer 180. In addition, the cigarette 200 may be inserted into the interior space of the aerosol-generating device 10.
The aerosol-generating device 10 shown in fig. 1 and 2 shows components related to the present embodiment. Accordingly, as will be appreciated by those of ordinary skill in the art to which the present embodiment relates, the aerosol-generating device 10 may also include other commonly used components in addition to those shown in fig. 1 and 2.
In addition, the aerosol-generating device 10 is shown in fig. 1 and 2 as including the heater 130, but the heater 130 may be omitted as desired.
Fig. 1 shows that the battery 120, the control part 110, the vaporizer 180, and the heater 130 are arranged in a row. Fig. 2 shows that the vaporizer 180 and the heater 130 are arranged in parallel. However, the internal structure of the aerosol-generating device 10 is not limited to the structure shown in fig. 1 or 2. In other words, the arrangement of the battery 120, the control unit 110, the vaporizer 180, and the heater 130 may be changed according to the design of the aerosol-generating device 10.
If the cigarette 200 is inserted into the aerosol-generating device 10, the aerosol-generating device 10 may operate the vaporizer 180 to generate an aerosol from the vaporizer 180. The aerosol generated by the vaporizer 180 is delivered to the user through the cigarette 200. The description of the carburetor 180 will be described in detail below.
The battery 120 supplies power for operating the aerosol-generating device 10. For example, the battery 120 may be powered to heat the heater 130 or the vaporizer 180 and may supply power required for the operation of the control portion 110. In addition, the battery 120 may supply power required for operation of a display, sensor, motor, etc. provided at the aerosol-generating device 10.
The control section 110 controls the operation of the aerosol-generating device 10 as a whole. Specifically, the control unit 110 controls the operations of the respective components in the aerosol-generating device 10 in addition to the battery 120, the heater 130, and the carburetor 180. The control unit 110 may also determine whether the aerosol-generating device 10 is in an operable state by checking the states of the respective components of the aerosol-generating device 10.
The control section 110 includes at least one processor. The processor may be implemented by a plurality of logic gate arrays, or may be implemented by a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. It should be understood by those skilled in the art that the present embodiment may be implemented by other hardware.
The heater 130 may be heated by power supplied from the battery 120. For example, the heater 130 may be located external to the cigarette when the cigarette is inserted into the aerosol-generating device 10. Thus, the heated heater 130 may raise the temperature of the aerosol-generating substance within the cigarette.
The heater 130 may be a resistive heater. For example, the heater 130 may include a conductive track (track) where the heater 130 is heated when an electric current flows. However, the heater 130 is not limited to the above example, and is not particularly limited as long as it can be heated to a desired temperature. Here, the desired temperature may be preset at the aerosol-generating device 10, or may be set by a user.
In one aspect, the heater 130 may be an induction heating heater, as another example. Specifically, the heater 130 may include an electrically conductive coil for inductively heating the cigarette, which may include a susceptor (heater) that is capable of being heated by the inductively heated heater.
The heater 130 is shown in fig. 1 and 2 as being disposed outside the cigarette 200, but is not limited thereto. For example, the heater 130 may include a tube-shaped heating member, a plate-shaped heating member, a needle-shaped heating member, or a rod-shaped heating member, and may heat the inside or outside of the cigarette 200 according to the shape of the heating member.
In addition, the aerosol-generating device 10 may be provided with a plurality of heaters 130. At this time, the plurality of heaters 130 may be provided to be inserted into the inside of the cigarette 200, and may be provided outside the cigarette 200. In addition, some of the plurality of heaters 130 may be provided so as to be inserted into the interior of the cigarette 200, and the remaining heaters may be provided outside the cigarette 200. The shape of the heater 130 is not limited to the shape shown in fig. 1 and 2, and may be made into various shapes.
The vaporizer 180 may heat the liquid composition to generate an aerosol, which can be delivered to a user through the cigarette 200. In other words, the aerosol generated by the vaporizer 180 is movable along the airflow path of the aerosol-generating device 10, which may be configured such that the aerosol generated by the vaporizer 180 is delivered to the user via the cigarette.
For example, the vaporizer 180 may include: the liquid storage part, the liquid transfer unit, and the heating member are not limited thereto. For example, the liquid reservoir, the liquid delivery unit and the heating member may be included as separate modules in the aerosol-generating device 10.
The liquid storage unit is capable of storing a liquid composition. For example, the liquid composition may be a liquid comprising tobacco-containing materials that contain volatile tobacco flavor components, and may also be a liquid comprising non-tobacco materials. The liquid storage part may be formed to be detachable from the carburetor 180 or attached to the carburetor 180, or may be formed integrally with the carburetor 180.
For example, the liquid composition may include water, solvents, ethanol, plant extracts, flavors, fragrances, or vitamin mixtures. The flavor may include menthol, peppermint, spearmint oil, various fruit flavor components, and the like, but is not limited thereto. The flavoring agent may include an ingredient capable of providing a variety of aromas or flavors to the user. The vitamin mixture may be a material mixed with at least one of vitamin a, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the liquid composition may include an aerosol former such as glycerin or propylene glycol.
The liquid transfer unit is capable of transferring the liquid composition in the liquid storage portion to the heating member. For example, the liquid transfer unit may be a core material (wick) such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, but is not limited thereto.
The heating member is a member for heating the liquid composition transferred by the liquid transfer unit. For example, the heating member may be a metal hot wire, a metal hot plate, a ceramic heater, or the like, but is not limited thereto. The heating member may be a conductive heating wire such as a nichrome wire, and may be wound around the liquid transfer unit. The heating member may be heated by the supplied electric current and transfer heat to the liquid composition in contact with the heating member to heat the liquid composition. As a result, an aerosol can be generated.
For example, the vaporizer 180 may also be referred to as an electronic cigarette (cartomizer) or an atomizer (atomizer), but is not limited thereto.
In one aspect, the aerosol-generating device 10 may further comprise other commonly used components besides the battery 120, the control portion 110 and the heater 130. For example, the aerosol-generating device 10 may comprise a display capable of outputting visual information and/or a motor for outputting tactile information. In addition, the aerosol-generating device 10 may comprise at least one sensor (puff detection sensor, temperature detection sensor, cigarette insertion detection sensor, etc.). The aerosol-generating device 10 may be configured to allow external air to flow in or internal air to flow out even when the cigarette 200 is inserted.
Although not shown in fig. 1 and 2, the aerosol-generating device 10 may be configured as a system with a separate carrier. For example, the cradle may be used to charge the battery 120 of the aerosol-generating device 10. Alternatively, the heater 130 may be heated in a state where the bracket is coupled to the aerosol-generating device 10.
The cigarette 200 may be a cigarette similar to a conventional combustion type cigarette. For example, the cigarette 200 may be divided into a first portion comprising aerosol-generating substances and a second portion comprising filters or the like. Alternatively, the second portion of the cigarette 200 may also include an aerosol-generating substance. For example, an aerosol-generating substance made in the form of particles or capsules may be inserted into the second part.
The interior of the aerosol-generating device 10 may be inserted throughout the first portion and the second portion may be exposed to the exterior. Alternatively, the interior of the aerosol-generating device 10 may be inserted into only a portion of the first portion, or may be inserted into both portions. The user can inhale the aerosol with the second portion gripped in the mouth. At this time, the external air generates an aerosol while passing through the first portion, and the generated aerosol is transferred to the user's mouth via the second portion.
As an example, the external air may flow in via at least one air passage formed in the aerosol-generating device 10. For example, the opening and closing of the air passage and/or the size of the air passage formed in the aerosol-generating device 10 may be adjusted by the user. Thus, the user can adjust the amount of atomization, smoking feeling, and the like. As another example, the external air may flow into the inside of the cigarette 200 through at least one hole (hole) formed on the surface of the cigarette 200.
An example of the cigarette 200 will be described below with reference to fig. 3.
Fig. 3 and 4 are diagrams showing an example of cigarettes.
Referring to fig. 3, a cigarette 200 includes a tobacco rod 210 and a filter rod 220. The first portion described with reference to fig. 1 and 2 includes a tobacco rod 210 and the second portion includes a filter rod 220.
The filter rod 220 is shown in fig. 3 as a single segment, but is not limited thereto. In other words, the filter rod 220 may be composed of a plurality of segments. For example, the filter rod 220 may include a first section for cooling the aerosol and a second section for filtering prescribed components included in the aerosol. In addition, the filter rod 220 may also include at least one segment that performs other functions, as desired.
The diameter of the cigarette 200 may be in the range of 5mm to 9mm and the length may be about 48mm, but is not limited thereto. For example, the length of the tobacco rod 210 may be about 12mm, the length of the first segment of the filter rod 220 may be about 10mm, the length of the second segment of the filter rod 220 may be about 14mm, and the length of the third segment of the filter rod 220 may be about 12mm, but is not limited thereto.

As an example, the cigarette 200 may be wrapped with a wrapper 240. As another example, the cigarettes 200 may be wrapped in overlapping fashion with more than two wrappers 240. For example, the tobacco rod 210 is wrapped with a first wrapper and the filter rod 220 is wrapped with a second wrapper. The tobacco rod 210 and the filter rod 220 wrapped with a single wrapper are combined and the entire cigarette 200 is repacked with a third wrapper. If the tobacco rod 210 or filter rod 220 is each made up of multiple segments, each segment may be individually wrapped in a single wrapper.

Fig. 5 is a block diagram schematically showing an example of the aerosol-generating device of the present invention.
Referring to fig. 5, an aerosol-generating device 10 according to the present invention comprises: a control section 110, a battery 120, a first heater 130, a pulse width modulation processing section 140, a display section 150, a motor 160, a storage device 170, and a carburetor 180. Next, the first heater 130 of fig. 5 is regarded as the same configuration as the heater 130 described in fig. 1 and 2. For convenience of explanation, general functions of each component included in the aerosol-generating device 10 will be explained first, and operations of the control unit 110 of the embodiment will be explained next in detail.
The control unit 110 integrally controls the battery 120, the heater 130, the pwm processing unit 140, the display unit 150, the motor 160, the storage unit 170, and the vaporizer 180 included in the aerosol-generating device 10 by generating and transmitting control signals. Although not shown in fig. 5, according to an embodiment, the control part 110 may further include an input receiving part (not shown) receiving a key input or a touch input of a user and a communication part (not shown) that may perform communication with an external communication device such as a user terminal. In addition, although not shown in fig. 5, the control part 110 may further include a module for performing proportional integral derivative control (PID) on the first heater 130.
The battery 120 supplies power to the heater 130, and the magnitude of the power supplied to the heater 130 can be adjusted by a control signal generated by the control unit 110. According to an embodiment, a voltage regulator (regulator) for maintaining a certain battery voltage may be included between the control part 110 and the battery 120.
When an electric current is applied, the heater 130 heats up through the inherent resistance and when the aerosol-generating substrate contacts (binds) the heated heater 130, an aerosol is generated.
The PWM processing unit 140 transmits a PWM (pulse width modulation ) signal to the heater 130, so that the control unit 110 can control the power supplied to the first heater 130 and the second heater 180 a. According to an embodiment, the pulse width modulation processing part 140 may be implemented by being included in the control part 110, and the PWM signal output from the pulse width modulation processing part 140 may be a digital pulse width modulation signal (Digital PWM Signal).
The display section 150 visually outputs various alarm information (alarm message) generated at the aerosol-generating device 10 so that a user using the aerosol-generating device 10 can confirm. The user can confirm the battery power shortage information or the overheat warning information of the heater or the like output to the display unit 150, and take appropriate measures before the operation of the aerosol-generating device 10 is stopped or the aerosol-generating device 10 is broken.
The motor 160 is driven by the control 110, and the user can identify the fact that the aerosol-generating device 10 is ready by tactile sense.
The storage device 170 stores various information so that the control section 110 provides consistent flavor to a user using the aerosol-generating device 10 by appropriately controlling the power supplied to the first heater 130 and the second heater 180 a. The storage 170 may be composed of not only a nonvolatile memory such as a flash memory (flash memory) in order to secure a faster data input output (I/O) speed, but also a volatile memory that temporarily stores data only when power is applied.
The vaporizer 180 may generate an aerosol by heating the liquid composition, and the generated aerosol may be delivered to a user via the cigarette 200. As depicted in fig. 1 and 2, vaporizer 180 may comprise: a liquid storage portion, a liquid transfer unit, and a heating member. In particular, the vaporizer 180 includes a heating member for heating the liquid composition stored in the liquid storage portion, and in fig. 5, the heating member for heating the liquid composition is shown as a second heater 180 a. The liquid storage part may be formed to be detachable from the vaporizer 180 or attached to the vaporizer 180, or may be formed integrally with the vaporizer 180.
The control section 110, the pwm processing section 140, the display section 150, the storage device 170, and the vaporizer 180 according to an embodiment of the present invention may be at least one processor (processor), or may include at least one processor. Accordingly, the control section 110, the pulse width modulation processing section 140, the display section 150, the storage device 170, and the carburetor 180 may be driven in a form included in another hardware device such as a microprocessor or a general-purpose computer system.
Next, the operation of the aerosol-generating device 10 will be described according to various embodiments.
The aerosol-generating device 10 in fig. 5 comprises: a first heater 130 for heating the cigarettes inserted in the first portion of the aerosol-generating device 10; a second heater 180a for heating the liquid composition stored in the cartridge removably mounted to the second portion of the aerosol-generating device 10; and a control part 110 controlling power supplied to the first heater 130 and the second heater 180 a. At this time, the control part 110 may control the power supplied to the second heater 180a based on the heating mode of heating the first heater 130, specifically, the pulse width modulation processing part 140 generates and transmits a PWM signal based on a signal transmitted by the control part 110, so that the power may be supplied to the first and second heaters 130 and 180 a.
First, the first portion is a portion into which the cigarettes described in fig. 3 and 4 are inserted, and when the cigarettes are inserted into the first portion, thermal energy of the first heater 130 is transferred to the cigarettes, and aerosol is generated by an aerosol-generating substrate included in the cigarettes. The second part is the position where vaporizer 180 depicted in fig. 1 and 2 is removed, and when the liquid composition stored in the cartridge (cartridge) of vaporizer 180 is exhausted, the user may temporarily remove vaporizer 180 located in the second part of aerosol-generating device 10 or the cartridge included in vaporizer 180, and reattach the vaporizer 180 or cartridge filled with the liquid composition to the second part.
According to the present invention, in controlling the power supplied to the second heater 180a by the control portion 110, by controlling the power supply to the second heater 180a based on the heating mode of the first heater 130, it is possible to provide a stable amount of atomization to the user compared to when the power supply to the second heater 180a is controlled regardless of the heating mode of the first heater 130. When the first heater 130 controlled by the control unit 110 to receive electric power is heated, the temperature inside the aerosol-generating device 10 increases according to the specific thermal conductivity and specific heat of the material of the aerosol-generating device 10, and such an increase in internal temperature also affects the increase in temperature of the second heater 180 a. According to the present invention, the control unit 110 can grasp the temperature rise in the aerosol-generating device 10 according to the heating mode of the first heater 130, and can supply appropriate electric power to the second heater 180a, so that the second heater 180a that heats the liquid composition can sufficiently heat the liquid composition of the cartridge.
As an alternative embodiment, the heating mode of the first heater 130 grasped by the control portion 110 may be a mode in which the reached preheating temperature is maintained for a certain time after the first heater 130 reaches the preset preheating temperature. For example, when the temperature of the first heater 130 reaches the preheating target temperature 260 degrees and is maintained for 3 seconds, the control part 110 may generate a power signal supplied to the second heater 180a based on the heating pattern of the first heater 130 and transmit it to the second heater 180a via the pulse width modulation processing part 140. At this time, the power signal of the second heater 180a corresponding to the heating mode of the first heater 130 may be generated based on information stored in the control part 110 in advance or information stored in the storage device 170 connected to the control part 110 through a wire or wireless.
As an alternative embodiment, the heating mode of the first heater 130 grasped by the control unit 110 may be a mode in which the internal temperature of the aerosol-generating device 10 measured by the temperature sensor exceeds a preset value as the preset preheating temperature is maintained for a certain period of time after the first heater 130 reaches the preset preheating temperature. In this alternative embodiment, the control part 110 detects that the internal temperature of the aerosol-generating device 10 rises as the first heater 130 is heated by the temperature sensor, and may control the power supplied to the second heater 180a by a process of judging whether the detected temperature exceeds a preset value.
In particular, according to this alternative embodiment, the control portion 110 may more accurately determine the power supplied to the second heater 180a through the double judgment step in the following manner: the first heater 130 is maintained for a certain time (first judgment) after reaching the pre-heating temperature, and the internal temperature of the aerosol-generating device 10 is detected to exceed a preset value (second judgment) based on the heating operation of the first heater 130. In this alternative embodiment, as an example of measuring the internal temperature of the aerosol-generating device 10, a temperature sensor may be attached to the cartridge storing the liquid composition, and according to an embodiment, at least one or more temperature sensors may be attached to the interior of the aerosol-generating device 10.
As an alternative embodiment different from the above embodiment, the heating mode grasped by the control portion 110 is a mode in which the internal temperature of the aerosol-generating device 10 exceeds a preset value after the first heater 130 reaches a preset preheating temperature, and the control portion 110 may reduce the power supplied to the second heater (reduction control) based on the heating mode.
Fig. 6 is a diagram for explaining a process in which the control section reduces control of the electric power supplied to the second heater.
Fig. 6 shows a graph of a first heater heating profile 610, a device temperature and cartridge container temperature 630, a liquid composition heater heating maximum power profile 650, and a liquid composition heater power profile 670 based on suction. In fig. 6, a graph of the first heater heating profile 610, the device temperature, and the cartridge container temperature 630 is interpreted according to the left temperature axis, a graph of the liquid composition heater heating maximum power profile 650 is interpreted according to the right power percentage axis, and a graph of the liquid composition heater power profile 670 is interpreted according to the suction.
First, according to the first heater heating case 610, the first heater 130 completes the preheating by maintaining the preheating target temperature for about 3 seconds after reaching the preheating target temperature 260 degrees at normal temperature. After the preheating is completed, the first heater 130 gradually reduces the temperature of the first heater 130 in stages and heats the aerosol-generating substrate included in the cigarette.
As can be seen from the graph of the device temperature and the cartridge container temperature 630, as the first heater 130 is heated, the device temperature and the cartridge container temperature slowly increase over time. After the device temperature and cartridge container temperature 630 reached about 50 degrees at about 27 seconds, they slowly increased with a decreasing temperature ramp. As described above, as the device temperature and cartridge container temperature 630 rise, the energy required for vaporization of the liquid composition decreases. That is, it is preferable that the control unit 110 reduces the power of the second heater 180a as the device temperature and the cartridge container temperature 630 increase. If the control part 110 does not reduce the power supplied to the second heater 180a, the fragrance of the aerosol may be changed due to excessive vaporization of the liquid composition, and the user's satisfaction with smoking may be reduced. Although the device temperature and cartridge container temperature are recorded in combination in fig. 6 for ease of illustration, only either one of the device temperature or cartridge container temperature may be employed according to an embodiment.
The graph of the maximum power heating by the liquid composition heater 650 is a graph showing the maximum amount of power supplied to the liquid composition heater, and the amount of power supplied to the second heater 180a is slowly decreased over time in inverse proportion to the increase in the device temperature and the cartridge container temperature 630.
The graph of the power situation 670 according to the sucked liquid composition heater does not show the graph of the maximum value of the power supplied to the liquid composition heater, but shows the graph of the variation of the power in detail, the rise and fall of the power supplied to the second heater 180a are faithfully reflected according to the user's suction and the lapse of time, and the maximum value of the power in each suction is bounded by the graph of the maximum power situation 650 of the liquid composition heater.
Unlike the above-described embodiment, the control section 110 may not grasp the internal temperature of the aerosol-generating device by the temperature sensor, but may use a value obtained by referring to a table concerning the temperature increase value of the aerosol-generating device 10. According to this alternative embodiment, without additionally providing a temperature sensor in the aerosol-generating device 10, when the temperature rise value of the first heater 130 reaches a specific value according to an experimental value, the internal temperature of the aerosol-generating device may be grasped by referring to a table stored in advance based on the temperature rise value.
TABLE 1
Example Temperature of the first heater Hold time Internal temperature estimation value of aerosol generating device
1 260 degrees 3 seconds 30 degrees
2 200 degrees 3 seconds 40 degrees
3 160 degrees 8 seconds 55 degrees
Table 1 shows an example of a table referred to by the control unit 110. When the temperature of the first heater is maintained in a state of reaching 260 degrees for 3 seconds or more, the control part 110 estimates that the internal temperature of the aerosol-generating device is 30 degrees, and supplies reduced power to the second heater 180a according to the estimated temperature. When the temperature of the first heater is maintained in a state of reaching 200 degrees for 3 seconds or more, the control part 110 estimates that the internal temperature of the aerosol-generating device is 40 degrees, and supplies reduced power to the second heater 180a according to the estimated temperature. The temperature of the first heater, the holding time, and the estimated value of the internal temperature of the aerosol-generating device described in table 1 may be different according to the embodiment. In addition, according to the embodiment, the control section 110 may reduce the power supplied to the second heater 180a based on only the temperature of the first heater and the estimated value of the internal temperature of the aerosol-generating device, or may reduce the power supplied to the second heater 180a in proportion to the rising value of the internal temperature of the aerosol-generating device when the first heater 130 reaches the preset warm-up temperature. As shown in table 1, when reduced power is supplied to the second heater 180a according to the internal temperature of the aerosol-generating device raised by the first heater 130, as the first heater 130 for heating the cigarettes is heated, a reduced portion of energy required when the second heater 180a for heating the liquid composition is heated is compensated for, so that the amount of atomization of the aerosol generated by the second heater 180a can be accurately adjusted.
As an alternative embodiment different from the above-described example, when the first heater 130 reaches the preset preheating temperature and is maintained for a certain time, the control part 110 may increase the power supplied to the second heater based on the heat energy transferred to the cigarette heated by the first heater 130.
Fig. 7 is a diagram for explaining a process in which the control section increases the power supplied to the second heater.
Fig. 7 shows a graph of a first heater heating profile 710, a central cigarette media temperature 730, a liquid composition heater heating maximum power profile 750, and a liquid composition heater power profile 770 based on draw. In fig. 7, a graph of the first heater heating profile 710, the central temperature 730 of the cigarette medium is interpreted according to the left temperature axis, a graph of the liquid composition heater heating maximum power profile 750 is interpreted according to the right power percentage axis, and a graph of the liquid composition heater power profile 770 is interpreted according to the draw. In the following, medium and aerosol-generating substrate are considered synonymous.
First, according to the first heater heating situation 710, the first heater 130 completes the preheating by maintaining the preheating target temperature for about 3 seconds after reaching the preheating target temperature 260 degrees at normal temperature. After the preheating is completed, the first heater 130 gradually lowers the temperature of the first heater 130 in stages and heats the medium included in the cigarette.
According to the graph of the central temperature 730 of the medium of the cigarette, the central temperature of the medium of the cigarette rises at a slope until a point of time of about 21 seconds elapses from the start of heating the first heater 130, after which the central temperature of the medium is maintained. As an example, the control unit 110 may obtain the sum of the heat energy transferred to the cigarettes by taking the integral value of the graph of the central temperature 730 of the cigarette medium.
According to the graph of the heating maximum power condition 750 of the liquid composition heater, the second heater 180a is heated from the time point when about 16 seconds elapse from the start of heating the first heater 130, and the maximum amount of power supplied to the second heater 180a is increased at a certain gradient from the time point when about 17 seconds elapse from the start of heating the first heater 130. Here, the point in time when about 17 seconds elapse since the start of heating the first heater 130 is a point in time when the control section 110 increases the power supplied to the second heater 180 a.
The graph of the power situation 770 of the liquid composition heater according to the suction is a graph showing not only the maximum value of the power supplied to the liquid composition heater but also the variation of the power per time in detail, and the rise and fall of the power supplied to the second heater 180a are faithfully reflected according to the suction of the user and the lapse of time, and the maximum value of the power in each suction is bounded by the graph of the heating maximum power situation 750 of the liquid composition heater.
As the first heater 130 is heated for a long period of time, the taste of the medium of the cigarette 200 becomes rich, and the amount of atomization of the liquid composition stored in the cartridge increases, so that a consistent smoking sensation can be provided to the user. That is, the aerosol inhaled by the user through the aerosol generating device is the sum of aerosols generated by heating the first heater 130 and the second heater 180a, respectively, and in order to provide the same degree of smoking satisfaction to the user each time, it is necessary to proportionally increase the amount of atomization by the second heater 180a according to the concentration of the aerosol that becomes concentrated as the first heater 130 heats the cigarettes. This alternative embodiment illustrated by fig. 7 is an embodiment designed according to the necessity as described above.
As a preferred embodiment of the present invention, when the first heater reaches the preset preheating temperature, the control part 110 may increase the power supplied to the second heater 180a based on the heat energy transferred to the cigarette after decreasing the power supplied to the second heater 180a in proportion to the rising value of the internal temperature of the aerosol-generating device.
Fig. 8 is a diagram for explaining a process in which the control section decreases the power supplied to the second heater and then increases again.
